@ponapalt I haven't, I don't really install that kind of software 🤔
This particular issue with the mouse dragging has only come up in the last week or two, I think. I want to say the first time I noticed it was right around the last couple of SSP updates. I had been dragging a balloon around while my other ghosts were still booting up (I boot multiple ghosts at once when I start SSP), and it seemed like that interruption got it stuck in dragging mode.
At the time, I figured it was a fluke due to me trying to adjust the balloon position before all of them had finished loading in. I'm not sure what caused it this time. I guess I did open a ghost right before it happened, but I wasn't even trying to move this ghost... I don't remember clicking on it at all.
